Examples
- Preparation and dielectric properties of mullite ceramic
莫来石陶瓷的制备及其微波介电性能研究 - Mullite ceramic composites fabricated by chemical vapor infiltration
用化学气相渗透法制备莫来石陶瓷基复合材料 - These powders transform to mullite completely at 1300 . the dielectric constant of mullite ceramics is related with their composition
热分析和xrd表明，该粉末经1300的热处理，就完全转变为莫来石。 - Using aluminium sulfate and colloidal silica as raw materials , another kind of mullite precursor powders is made . the relative density of silica - rich mullite ceramic sintered from these powders at 1550 for 1 hour with a pressure of 15mpa is 97 %
以硫酸铝、硅溶胶为原料，采用溶胶-凝胶法制备了莫来石先驱体粉末，所得富硅莫来石先驱体粉末在1550 、 15mpa下热压烧结1小时后，致密度达97 。 - The dielectric constants of silica - rich , alumina - rich , and stoichiometric mullite ceramics are 5 . 5 , 6 . 0 and 6 . 3 respectively . the dielectric constant of mullite - si / c / n composites is related with the sintering parameters . with the increase of the sintering temperature and dwelling time , the " " and tg of mullite - si / c / n composites are decreased , this phenomenon is related with the change of the microstructure and phase composition of nano si / c / n powders
莫来石- si c n复合材料的介电常数与热压烧结工艺有很大的关系，随热压烧结温度( 1450 1600之间)的升高，烧结时间(烧结温度为1550 )的增长，莫来石- si c n复合材料的介电常数实部、虚部及介电损耗角正切均明显下降，这与吸收剂的性质随温度和时间的变化有关。
